Three others again from, Sweden? Our member "steelcharge" on the Graybeard forum must be Swedish because he finds these things with ease. A search of the "Digitalmuseum" of the Armeemuseum for the Swedish word for canister round gave me 13 pages and probably over 200 projectiles, but a number are too modern to be within scope for this forum. However the three at these links are within the family under discussion. I did not pull out any photos for separate posting because I know if it was appropriate to do here, Michael can do it much more efficiently than I can. One thing I like about Sweden is that the colder-average (and perhaps dryer) environment preserves things beyond the age at which any similar items in warmer, more humid countries have long-since disintegrated.
Also, sorry but I can't remember if I ever posted this video here before. It shows a group of us firing home-made canister rounds from an antique bronze swivel gun with about a 2 1/8-inch bore. As you can see the canister rounds we made were very simple yet they functioned effectively.
